Carlo Gavazzi has launched its latest transducers the ET112 and ET340, designed for both single and three phase energy monitoring applications.
Particularly suited for active energy metering and cost allocation in applications up to 100 A for the ET112 and 65A for the ET340 (direct connection), class 1 accuracy with import/export and dual tariff management. The exclusive optical port also allows simple and fast programming of the parameters, variable reading and data logging with the relevant OptoProg optical adapter.
Both the ET112 and ET340 offer fast and simple installation, thanks to the transducers self-power supply from the voltage reference inputs, automatic phase detection with wrong-phase-sequence warning and fast application-oriented programming procedure.
Measuring kWh, kvarh imported and exported energy, the transducer is optionally provided with pulse output, RS485 Modbus port and if space is ever a problem then the ET112 is only 2 DIN wide and 3 DIN wide for the 65A ET340.
A selection of variables can be programmed providing for active and reactive energy measurement, options include: system variables such as kW, kvar, kVA, VLL, VLN, PF, Hz, kWdmd, kWdmd peak and hour run as well as phase variables including kW, kvar, kVA, VLL, VLN, A, PF and THD. Energy measurement: kWh and kvarh (imported/ exported); kWh+ by 2 tariffs; and the ET340 has kWh per phase.
